Working Principle of the SG-30-D

The SG-30-D operates according to three principles: voltage regulation, current limiting, and protection from electrostatic discharge. It is designed with an input terminal where the input signals are monitored and then regulated to an acceptable output level. Voltage regulation is maintained by an adjustable voltage regulator, while the current limiting is provided by a PTC thermistor. This thermistor acts as a fuse to protect the components of the circuit from damage caused by excessive currents.

The SG-30-D also provides protection from electrostatic discharge. This protection is provided by a discharge tube that allows static electricity to be drained away from the circuit components. This helps to protect the components from experiencing permanent damages due to receiving high voltage static charges.

Conclusion

The SG-30-D is an electrical accessory device that is used in a variety of applications. It is designed to provide reliable voltage regulation and current limiting protection. It also offers protection from electrostatic discharge. These features make it a useful and reliable accessory device in various applications.
